Dorman - OE Solutions Wheel Bearing and Hub Assembly P/N:686-438
Cut the labor out of a seized rear hub job with the Dorman - OE Solutions Wheel Bearing and Hub Assembly 686-277, a rear left loaded steering knuckle that drops in as a direct-fit replacement for the 2011-2019 Ford Explorer. On many Explorers rust builds between the steering knuckle and the wheel hub bearing until the two seize together — a common problem in Salt Belt regions that can also develop under normal use — often making the original knuckle difficult or impossible to salvage. This pre-assembled unit sidesteps that.
Signs a rear hub bearing may need replacing include a humming or growling that changes with speed, wheel play, or a rear ABS fault.
